新发水库重力坝三维有限元仿真分析

The finite element simulation analysis of Xinfa gravity dam

结合工程实例,采用三维有限元软件(ANSYS)对重力坝在3种工况下的应力应变进行了分析。计算结果表明:坝体的应力分布符合有限元计算的一般规律,反映了重力坝的实际应力分布情况,验证了方案的可行性,为该重力坝的设计提供依据。运用有限元软件(ANSYS)对重力坝应力应变进行计算可节约时间,提高工作效率,具有较大的实用价值。

Combined with practical engineering, we analyzed the stress and strain under 3 working conditions of gravity dam by the finite element software （ANSYS）. The results show that the stress distribution of the dam body accords with the general rules of FEM （finite element method） and reflects the actual stress distribution of gravity dam, the result validated the feasibility of the project and provided the basis for the design of the gravity dam. The stress and strain of gravity dam was analyzed using finite element software （ANSYS） not only can improve calculating speed ,but also can increase efficiency greatly, which will has a high practical value.
